Abstract: To improve the speed of data acquisition and real-time video transmission, Filed Programmable Gate Array (FPGA) as the core processor, the Verilog HDL was used to describe the circuit function realization to realize the high-speed access of Synchronous Dynamic Random Access Memory (SDRAM) based on a typical network real-time transmission network multimedia service data. The new high-speed real-time transmission of video data took full advantage of the characteristics of FPGA parallel processing to improve video data acquisition and transmission rates. The experimental results demonstrate the effectiveness of the method.

Graduate Theses and Dissertations
The work presented in this thesis was aimed at the development of a hardware accelerator for the Digital Image Correlation engine (DICe) and compare two methods of data access, USB and Ethernet. The original DICe software package was created by Sandia National Laboratories and is written in C++. The software runs on any typical workstation PC and performs image correlation on available frame data produced by a camera. When DICe is introduced to a high volume of frames, the correlation time is on the order of days. The time to process and analyze data with DICe becomes a concern when …

Abstract: In the power system, electronic current transformer based on the Rogowski coil has been widely used in digital substation. Based on the analysis of its composition and structure, the electronic transformer is simulated by the Simulink module in Matlab. Rogowski coil is used to simulate the traditional transformer. Using Σ-Δ ADC converter and digital filter, analog signal from the high-pressure side is converted to digital output data, which is sent via fiber optic Ethernet to FPGA development board after FT3 format framing by Simulink. The data is then sent to the merged unit of transformer’s interface after Manchester encoding …
